Mariana is featured in The Sims 2 as one of the pre-made deceased ancestral Sims in Pleasantview, one of the neighborhoods shipped with the game. Although she is deceased when the game begins, she appears in the family tree of her grandson Dirk Dreamer. According to Mariana's SimDNA in SimPE, her hair was black before it turned grey, meaning that she probably dyed it brown in The Sims 3. She is the only known ancestor of Dirk that does not have dark skin. According to Mariana's age data, she had 30 days left in the elderlife stage when she died.

Like most pre-made deceased Sims from The Sims 2, she is completely unplayable without the use of hacks or third party programs, such as SimPE. Her grave can not be found anywhere, so it was most likely deleted. Though Mariana's character data was deleted, regenerating her with SimPE is a tad easier than most dead ancestors, as her facial features are almost, if not identical to that of the 9th Maxis face template in Create a Sim, unlike most "unresurrectable" Sims that have customized facial features.
